SPECPICATION forming part of Letters Patent No. 373,824, dated November 29, 1887. Application filed December 1li, 1886. Serial No. 221,520. (No mcdel.)

To aZZ whom it may concern..-

Be it known that I, CrrARLns P. GAY, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Double-Acting Sash-Holders; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain novel improvements in double-acting sash-holders; and it consists, essentially, in the combination, with an angular base-plate and spring actuated arms or dogs pivoted therein, of a slightlyelastic cap inclosing the workingface of' each arm and an adj ustably-mounted screw adapted to lock the arm in position.

The object of my present improvements is to provide the upper and lower weighted sashes of windows with means whereby both sashes may be more readily adj usted and effectually locked in position.

In the accompanying sheet of drawings, illustrating my invention, Figure l represents a plan View of the device attached to the top surface of the lower weighted sash, the upper sash and window-casing being shown in horizontal section. Fig. 2 is a side view of the same, showing one of the elastic caps in section and bearing against the upper sash as in use. Fig. 3 is a front view showing the other working-arm bearing against the inner vertical face ofthe casing. Fig. 4 is a vertical longitudinal sectional view taken through a: fr of Fig. 1, with the auxiliary locking device and one arm removed,the elastic cap being in elevation.

Fig. 5 is a detached perspective view of the elastic cap. Fig. 5iis a partial transverse sectional View taken on line o o of Fig. 4. Fig. 6 is a transverse sectional view, showing a modified form ofthe device for locking the arm in position; and Fig. 7 is a plan View thereof.

The following is a more detailed description ofthe invention, including the manner of itsoperation.

A, referring to the drawings, designates my improved double-acting sash-lock as a whole. Y l ct indicates the Vmetallic base-plate, the same having an angular form or outline (see Fig. l) and provided with l the two sets of vertical sides a', arranged at right angles to each other and having pins p therein. The front end portions of the angular base are slightly raised and provided with openings h, adapted to rcceive the bent end e of the fiat metal spring e, (one being shown in Fig. 4.) B B designate the arms or dogs pivoted to the baseplate a by means of said .pins p. The front or free end, b2, of each arm is made slightly eccentric and somewhat elongated, the circumscribing faces of the said elongated portion b2 being beveled (see Figs. 2 and 5t) to form a better holdingsurface for the removable caps, about to be described. The rear ends, b, of the arms are flattened, which, in connection with the sp rings e, prevent them from accidentally falling. (See dotted position, Fig. 4.) The free end of the arm is elongated, as at bf, for the purpose of affording a convenient handle to take hold of in disengaging or unlocking the arm from the window casing or jamb.

C indicates the cap, made of stiff rubber or other suitable material possessing slightlyelastic properties. The cap is made hollow or chambered, as at c, to fit ther said beveled portion b2 of the arms, the contracted sides of the cap being sprung over the same. The working-face c2 ofthe cap is slightly roughened or corrugated, its contour closely following that of' the adjacent portion of the arm.

On the inner sideof one of the holders is formed a projection, n, which is tapped to receive a screw, D, the head of the latter being elongated to extend over the top of the adjacent arm. (See first three figures.) By means of this attachment the sash, supported by said arm, is prevented from being lifted, while at the same time the eccentricity of the arm precludes its being forced downward. In Figs. 6 and 7 I have shown a modified form of the locking device, the same consisting of the loose plate D', through which ascrew, r, loosely passes to engage the tapped boss n, the nut r2 serving to clamp the plate in roo position over the arm B.

Now, assuming the improved sashlock A to be secured to the lower sash, as represented, the manner of its operation is substantially as follows: IVhen used as a lock to keep the upper and lower sashes closed, the two arms B B are dropped, one to engage the upper sash, s, and the other to engage the easing or windowj amb F, the compressible caps C being directly in contact with said sash and casing. Of course any upward pressure applied to the lower sash tends to more rnily lock the parts together.

It is obvious that by swinging the arms B upward (see dot-ted position, Fig. 4) either or both sashes may be moved up and down, as desired, after which, when the proper adjustment has been attained, thc sashes are locked in position by simply dropping the arms B into engagement with the respective sash and `iamb. The arm bearing against the upper sash is then more e'ectually retained in position by turning the head ofthe screw D partly around, so that its under side engages with the upper surface of the arm.

By means of this auxiliary locking device it is rendered impossible to unlock the sash from without by inserting a thin piece of metal between the two saslies against the holding-arm.

rIhe removably-secured elastic cap C furnishes a comparatively large bearing-surface, the internal shape being such that the cap remains in position upon the arm, even under great pressure.

I do not claim, broadly, a double-acting sash-lock; but

Vhat I do claim, and desire to secure by United States Letters Patent, is

l. rIlhe angular double acting sash -lock hereinbefore described, consisting of the baseplate, lockingarms mounted at right angles to cach other in said plate, removably-secured semi-elastic caps adapted to engage the sash and jamb, covering the working-face of the arms, an auxiliary locking device or devices adapted to retain the arms in theloeked position, and springs adapted to hold the arms in the normal or unlocked position, the whole constructed, arranged, and operati ng substantially as shown and set forth.

2. The combination, with the angular base and arms B B mounted therein at right angles to each other, of the auxiliary locking device consisting of an adjustablymounted screw having its head elongated to engage the arm B, substantially as shown, and for the purpose hereinbefore set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.
